[0027] like Figures 1 to 4 As shown, a cleaning device for ventilation ducts includes a pull rod 1, and a cleaning mechanism 2 for cleaning debris accumulated on the inner wall of the rectangular ventilation duct is installed on the front of the pull rod 1. Through holes are opened inside the cleaning mechanism 2 and the pull rod 1, and a spray brush mechanism 5 is installed inside the through holes of the cleaning mechanism 2 and the pull rod 1. The spray brush mechanism 5 is located on the side of the cleaning mechanism 2 away from the pull rod 1; specifically, by starting the cleaning mechanism 2, the upper and lower left and right outer surfaces of the cleaning mechanism 2 are respectively abutted against the upper and lower left and right inner walls of the rectangular duct, so that subsequent staff can scrape off the debris accumulated on the inner wall of the rectangular duct when pulling or pushing the pull rod 1, thereby completing the cleaning of the inner wall of the rectangular duct; the position of the upper and lower left and right outer surfaces of the cleaning mechanism 2 can be adjusted and moved, so that the cleaning mechanism 2 can clean various types of rectangular ducts during use, thereby expanding the applicability of the device.

[0028] like Figures 1 to 3As shown, the cleaning mechanism 2 includes a fixed block 201, which is mounted on the front side of the pull rod 1. Electric telescopic rods 202 are provided on the outer surfaces of the upper, lower, left and right sides of the fixed block 201. The output ends of the four groups of electric telescopic rods 202 are all installed with fixed plates 203. The four groups of fixed plates 203 are each provided with a two-way electric telescopic rod 204 on the side away from the fixed block 201. The output ends of the two sides of the four groups of two-way electric telescopic rods 204 are all installed with trapezoidal positioning blocks 205. The two adjacent groups of trapezoidal positioning blocks 205 are each provided with a connecting block 207 on the side away from the fixed block 201. A telescopic scraper 206 is installed between the adjacent sides of the two adjacent groups of connecting blocks 207. Specifically, the four groups of fixed plates 203 are driven to enter the interior of the pipe by pushing the pull rod 1, and then the four groups of electric telescopic rods 202 and the four groups of two-way electric telescopic rods are activated. The rod 204 pushes the four groups of fixed plates 203 and the eight groups of trapezoidal positioning blocks 205 to move, and fits the adjacent sides of the two adjacent groups of trapezoidal positioning blocks 205 at the four corners in the pipe together, so that the four groups of telescopic scrapers 206 are respectively in contact with the upper, lower, left and right inner walls of the rectangular pipe away from the side of the fixed block 201, so that the subsequent staff can scrape off the debris accumulated on the inner wall of the rectangular pipe in the process of pulling or pushing the pull rod 1, thereby completing the cleaning of the inner wall of the rectangular pipe; by starting the four groups of electric telescopic rods 202 and the four groups of two-way electric telescopic rods 204 to drive the four groups of telescopic scrapers 206 to expand and contract and drive the position of the four groups of telescopic scrapers 206 to adjust and move, the cleaning mechanism 2 can clean various types of rectangular pipes during use, thereby expanding the applicability of the device.

[0029] like Figure 1 and Figure 4 As shown, the brushing mechanism 5 includes a connecting pipe 501 and a fixed pipe 502, a through hole is opened on the front of the fixed block 201, the position of the through hole inside the fixed block 201 is parallel to the through hole inside the pull rod 1, the fixed pipe 502 is installed inside the through hole of the pull rod 1 and the fixed block 201, the connecting pipe 501 is installed at the water inlet end of the fixed pipe 502, and the outer surfaces of the upper, lower, left and right sides of the fixed pipe 502 are all provided with nozzles 503; specifically, the water flow is introduced into the interior of the four groups of nozzles 503 through the connecting pipe 501 and the fixed pipe 502, and then the positions of the four groups of nozzles 503 are arranged in front of the four groups of telescopic scrapers 206, so that the liquid sprayed by the four groups of nozzles 503 pre-cleans the inner wall of the pipe before the subsequent four groups of telescopic scrapers 206 clean the inner wall of the pipe, so that the subsequent four groups of telescopic scrapers 206 can quickly scrape off the debris accumulated on the inner wall of the pipe during the pushing process, thereby improving the efficiency of the subsequent cleaning mechanism 2 in cleaning the inner wall of the pipe, thereby improving the practicality of the device.

[0030] like Figure 2As shown, a U-shaped groove is provided on one side of the fixed block 201 close to the nozzle 503, and the U-shaped protective plate 6 is clamped inside the U-shaped groove of the fixed block 201; specifically, when the device is subsequently idle and stored, the U-shaped protective plate 6 is pushed and clamped inside the U-shaped groove of the fixed block 201, so that the position of the U-shaped protective plate 6 is installed and positioned at the outer end of the four groups of nozzles 503, so that the subsequent U-shaped protective plate 6 can shield and protect the four groups of nozzles 503 during use, thereby minimizing damage to the subsequent spray brush mechanism 5 after being hit during idle storage.

[0031] like Figure 1 As shown, a rubber sleeve 3 is bonded to the outer surface of the pull rod 1; specifically, the rubber sleeve 3 is positioned on the outer surface of the pull rod 1, so that when the subsequent staff pushes or pulls the pull rod 1 to drive the cleaning mechanism 2 to move, the rubber sleeve 3 increases the friction between the pull rod 1 and the staff's hand, thereby minimizing the subsequent staff's hand from sliding on the outer end of the pull rod 1 when the cleaning mechanism 2 moves by pulling or pushing the pull rod 1, thereby improving the comfort of the subsequent staff when pushing or pulling the pull rod 1.

[0032] like Figure 1 As shown, a groove is provided on the outer surface of the pull rod 1, and a control panel 4 is provided inside the groove of the pull rod 1. The control panel 4 is located at the end of the rubber sleeve 3 away from the cleaning mechanism 2; specifically, the control panel 4 is located on the side of the pull rod 1 close to the user's hand, so that subsequent staff can operate the control panel 4 to adjust the volume of the cleaning mechanism 2, and then enable subsequent staff to quickly pull the cleaning mechanism 2 out from the inside of the rectangular pipe, thereby reducing the labor consumed by subsequent staff in moving the device out of the rectangular ventilation duct.

[0033] In summary: by pushing the pull rod 1, the four sets of fixed plates 203 are driven to enter the interior of the pipe, and then by starting the four sets of electric telescopic rods 202 and the four sets of two-way electric telescopic rods 204, the four sets of fixed plates 203 and the eight sets of trapezoidal positioning blocks 205 are pushed to move, so that the adjacent sides of the two adjacent sets of trapezoidal positioning blocks 205 at the four corners in the pipe are fitted together, so that the four sets of telescopic scrapers 206 away from the fixed blocks 201 are respectively in contact with the upper, lower, left and right inner walls of the rectangular pipe, so that the subsequent staff can scrape the four sets of telescopic scrapers 206 when pulling or pushing the pull rod 1, thereby completing the cleaning of the inner wall of the rectangular pipe; by starting the four sets of electric telescopic rods 202 and the four sets of two-way electric telescopic rods 204, the four sets of telescopic scrapers 206 are driven to expand and contract and the positions of the four sets of telescopic scrapers 206 are adjusted and moved, so that the cleaning mechanism 2 can clean various types of rectangular pipes during use, thereby expanding the applicability of the device.

[0034] At the same time, water flow is introduced into the interior of the four groups of nozzles 503 through the connecting pipe 501 and the fixed pipe 502, and then the position of the four groups of nozzles 503 is set in front of the four groups of telescopic scrapers 206, so that the subsequent four groups of telescopic scrapers 206 clean the inner wall of the pipe. The liquid sprayed by the first four groups of nozzles 503 pre-cleans the inner wall of the pipe, so that the subsequent four groups of telescopic scrapers 206 can quickly scrape off the debris accumulated on the inner wall of the pipe during the pushing process; by pushing the U-shaped protective plate 6, the U-shaped protective plate 6 is clamped in the U-shaped groove of the fixed block 201, so that the position of the U-shaped protective plate 6 is installed and positioned at the outer end of the four groups of nozzles 503, so that the subsequent U-shaped protective plate 6 blocks and protects the four groups of nozzles 503 during use, thereby minimizing damage to the subsequent spray brushing mechanism 5 after being hit during idle storage.
